Connectors are words or phrases that link ideas, sentences, or paragraphs together in writing. They help to create a smooth flow of thoughts, making it easier for readers to understand the relationships between different parts of a text. Common examples of connectors include words like "and," "but," "however," and "therefore." In addition to linking ideas, connectors can also indicate the type of relationship between them. For instance, cause and effect connectors like "because" or "as a result" show how one idea leads to another. Similarly, contrast connectors like "on the other hand" highlight differences between concepts.
